CAR-WALL STRUCTURE.

Application led September My invention has for its object to provide nall metal car construction of novel char- !cter which is unusuallystrongfor its weight and durable throughout, which may be conveniently andeconomically manufactured and transported, is weather proof and whichpossesses certain other desirable and advantageous features to behereinafter described and claimed. My sheet metal wall structure isapplicable to the end or side of box, automobile, gondola, stock or anyother type of railway car equipment.l

The ends of'railway cars are subject to considerable stress due to theshifting of the lading. These blows are imparted to the end over theentire area thereof, or to local areas. Threat is loaded tosubstantially the top of Vthe car which causes all the blow to beimparted'over the entire area ofthe end. Lumber is loaded to the top anoupon impact the top boards shift causing ablow to be imparted at the topof the end. Sand, chats and other plastic loads and light pipe'causeblows at the middle of the car, whereas-rail,

steel plates, castings and the like cause blows at the bottom ofthe car.l

`While, of course, efforts are made to block the lading in the car, theheavy locomotives, the emergency air brake and the classification humpbreak the lading 'away from its moorings and throw it against the `endof the car.

A rigid end to a car, and particularly a large box car, materiallystrengthens the entire superstructure to resist the torsional andweaving movements which not only rack the car to pieces, but causesleaky roofs and inoperative and leaky doors with their consequent damageclaims. As it costs as much to transport a ton of freight car as it doesa ton Y y of lading it is imperative that the weight of the car must bekept as low as possible, therefore, the end must be very light as wellas strong. As freight cars are frequently damaged in wrecks and by otherunfair usage, any end will be damaged in service, therefore, it must becapable of being easily` repaired with Vsuch meagre facilities as therailroads are equippedrwith at their outlying repair points.

My wall is `made ofV one or more metallic plates' with their meetingsides overlapped and lured together, the overlappedportions 26, 1925.serial No, 58,845.

being formed to provide members which act as columns to sustain the roofload, as beams to resist the thrust of the lading and as stieners toprevent buckling of the wall. rlhese beam-columns are so formed as toprovide ventilators or tlues from the exterior to the interior of thecar. Such ventilation is desirable because it prevents the condensationof moisture in the air within the car, which would injure some types oflading.

An object of the inventionis to form the overlapped portions of themetallic plates of a railway ca r wall so as to provide a beamcolumnwhich also .furnishes means of ventilation for the car.

The Interstate Commerce Commission has prescribed the minimum clearancesbetween freight cars in their order of March 13, 1911, which reads asfollows:

No part of car above end-sills withinV thirty (30) inches from side ofcar, except buffer-block, brake-shaft, brake-wheel, brakestep,running-board or uncoupling lever shall extend to within twelve (12)inches of a vertical plane parallel with end of car and passing throughthe inside face of knuckle when closed Vwith coupler-horn against thebuffer-block or end-sill, and no other part of end' of car or fixtureson same above end-sills, other than exceptions herein noted, shallextend beyond the outer face of buffer-block.

-Any reinforcement in the wall not within thirty (30) inches from thesides of the car may extend to the face of the buffer block. An objectof the'invention is to take advantageY of this condition and to make thebeamcolumns deeper' near the middle of the car than within thirty (30)inches from the side of the car.

`Theouter corrugated plate prevents rain, falling cinders or the likefrom entering the iues and the inner corrugated plate prevents sand,grain or similar lading from escaping from the car through the flue.

Another object of theinvention is to arrange the lining boards so as topermit of a deeperbeam-column near the middle of the car than elsewhere.

Another object of the invention is to provide primary reinforcementsextending substantially from the underframe to the ridge pole or otherroof framing, which members forni excellent anchorage 'and also provideother secondary reinforcements parallel to and spaced apart form theprimary reinforcements. These reinforcements vary in depth and widthaccording to conditions.

I have used the terms plates and sheets to simplify the claims, butthere is no dit'.- 'erence in their meaning as far as this invention isconcerned.

These reiniiorcenients or corrugations may be rectangular, asillustra-ted, or circular, or of any other desired contour.

In .the drawings 1 shows the end of a railway car with my improved Vallapplied thereon.

Fig. 2 is a section on line 2-2 ot Fig. 1

Fig. 3 is a section on line 3-3 o'lilig. 1.

Fig. i shows a modified form.

Fig. 5 shows a modiiied form.

Fig. (3 is a perpective view ot one of the plates.

For convenience, I have shown an end wall of `a. box carwherein 1 .isthe end sill; 2 the end plate; 3 the corner post; fl the butler block;the end ladder; VG the underirame; 7 the ridge pole and 8 the sideplate.

The wall comprises a plurality of inetallic plates 10, 11 and 12, someof which have one or more inwardly projecting corrugations 13 whichterminate within the lower edge but extend to the upper edge of theplate and othersV ot' which have one or lre outwardly projectingcorrugations 14 ich terminate within lthe upper edge but e v`end to thelower edge of the plate. These lcorruge-.tions are positioned oppositeeach other and the plates are secured together on both .sidesy oi thecorrugations so as to form a box girder.v The corrugation 14 on theoutside of the wall is open at the bottom and closed at the top, Vwhilethe corrugation 13 on the inside ot' the wall is of reverse formation,te.; closed at the bottom and open at the top, thus .forming aVentilating communication between the exterior and interior ol thecar.-V

The wall may be made ol a pair of corrugated plates 1 5-16 or 17-18 eachhaving a small flange on each side of the corrugavtion, which. flangesare ysecured together to t'orm a beamcolumn and flat plates 19 areinsertedL between the flanges and spans the distancev between therespective beam-columns. Such va construction is shown in Fig. 5.

VIt may be desirable'to orm a corrugation near each side of a plate andposition such corrugated plates with oppositely projecting lcorrmentionsin the overlapped portions of adjacent plates. Such a construction isshown in l? 8.

t may he desirable to form the plate (20) with an inwardly projectingcorrugation 13 near one edge andan outwardly projecting corrugation 14Cnearthe other edge and position suchplates with opposite'ly projectingcorrugations in the overlapped portions of adjacent sheets. Such vaconstruction shown in Fig. 4.

Fig. 6 shows one of the plates 20 of the construction illustrated inFig. 4l wherein the corrugation 13 near the side 21 ofthe plateterminates within-the lower edge but extends to the upper edge ot' theplate, and the corrugation 14 near the other side 22 of the plateterminates within the upper edge to shear oil this Hare but to utilizeit to i obtain greater riveting area, as shown .in Fig. 1.

The filler blocks or nailing of the same depth as the inwardlycorrugations so that the lining bear agzjainst and are supported bythese corrugrations. The nailing strips are held in place by bolts 26.-

The accompanying drawings illustrate the strips 27 are vproject in gpreferred form of the invention, though it to be understood that theinventionv is not limited to the exact details of construction shown anddescribed, as it is obvious that various modifications thereof withinthe scope of the claims will occur to persons skilled in the art. f
